“…In wastewater, these microplastics are present with a diverse range of pharmaceuticals that can adsorb to their surface (McDougall et al 2021). Pharmaceuticals, by their very nature, can induce effects to exposed organisms once in the environment (Wang et al 2021).…”

There are concerns that microplastics act as a vector of pharmaceuticals in the aquatic environment. Most studies have focussed on pharmaceutical adsorption and have not investigated desorption in the various matrices that microplastics enter. Therefore we studied the desorption of the antidepressant drug fluoxetine from polyethylene terephthalate (PET) microplastics in river water, sea water, and simulated gastric and intestinal fluids. We found that most desorption occurred rapidly, within a few hours of exposure. Fluoxetine desorption fitted well to the Freundlich isotherm with r2 values ranging from 0.97 to 0.99. Desorption decreased in the following order: gastric fluid at 20 °C and 37 °C; sea water at 20 °C; intestinal fluid at 20 °C and 37 °C; then river water at 20 °C. The little difference in desorption in gastrointestinal fluids at 20 °C and 37 °C suggests a similar exposure risk to cold- and warm-blooded organisms following PET microplastic ingestion. Total desorption following sequential incubation 2 h in gastric fluid then 4 h in intestinal fluid to mimic gastrointestinal digestion was 37% at 20 °C and 41% at 37 °C. Interestingly, higher desorption of 18–23% occurred in sea water compared to river water, of 4–11%. Under a worst-case scenario, more than 44 mg kg−1 body weight d−1 or more than 52 mg kg−1 body weight d−1 of PET microplastics from river water or sea water, respectively, need to be consumed to exceed the mammalian acceptable daily intake for fluoxetine. Further studies are needed on microplastic ingestion and the bioavailability of adsorbed pharmaceuticals to a range of exposed aquatic organisms.

“…As WWTPs were not designed to remove pharmaceuticals, many of these compounds are frequently detected in WWTP effluents at levels ranging from sub-ng/L up to several µg/L [1]. The release of pharmaceuticals into rivers and lakes is becoming an alarming issue because they are a threat to the health of living beings, including humans [2][3][4][5][6][7][8]. Groundwater contamination has also been reported.…”

A Three-Dimensional Electrochemical Process for the Removal of Carbamazepine

et al. 2021

The scientific community is increasingly concerned about the presence of pharmaceuticals in the aquatic environment, which is a consequence of their high consumption and inefficient removal by wastewater-treatment plants. The search for an effective and sustainable tertiary treatment is therefore needed to enhance their removal. For this purpose, the combination of electrochemical and adsorption processes into three-dimensional (3D) electrochemical systems has been proposed. In this study, a 3D system was studied to remove carbamazepine, an antiepileptic, consumed in high doses and very persistent in the environment. The influences of the following parameters on its removal were evaluated: anode and cathode materials and distance between them, electrolyte (NaCl) concentration and pH, and the (carbon-based) adsorbent material used as the particulate electrode. The obtained results demonstrated that the introduction of the particulate electrode improved the removal efficiency. This can be attributed to the simultaneous occurrence of different phenomena, such as adsorption/electrosorption, electrocoagulation, oxidation, and catalytic degradation.

“…This need lies in the fact that most emerging organic pollutants, such as pharmaceuticals, antibiotics, pesticides, etc., are resistant, toxic, and exhibit low biodegradability. As a result, it is practically difficult degrade them with conventional methods [2][3][4]. As effective methods of decontamination of water and wastewater, advanced oxidation processes (AOPs) are widely applied for the degradation of various resistant pollutants through the formation of reactive oxidant species (ROS), such as hydroxyl ( • OH) or sulfate radicals (SO 4…”

“…The formation of sulfate radicals is of particular interest to the scientific community, mainly because of the advantages they exhibit over hydroxyl radicals. Some of the main disadvantages of the decontamination methods based on • OH radicals are the limited pH range (2)(3)(4) and the creation of sludge in the case of photo-Fenton process [12] and generally the shorter half-life of • OH radicals [13].…”

Heterogeneous Activation of Persulfate by LaMO3 (M=Co, Fe, Cu, Mn, Ni) Perovskite Catalysts for the Degradation of Organic Compounds

et al. 2022

View full text Add to dashboard Cite

Sulfate radical-based advanced oxidation processes (SR-AOPs) are lately applied for the degradation of various pollutants through the formation of reactive oxidant species (ROS) from activation of oxidants, such as persulfate (PS) or peroxymonosulfate (PMS). In this study, LaMO3 (M=Co, Fe, Cu, Mn, Ni) perovskite catalysts were synthesized, characterized by several techniques, and tested for the activation of persulfate towards the degradation of phenolic pollutants. The effect of substitution of position B of La-based perovskites as well as calcination temperature was studied. Overall, the results showed that the decisive role in the catalytic activity was the presence of structures that enhance the transfer of electrons between perovskite and oxidant. LaNiO3 followed by LaCoO3 were found as the most active catalysts. Finally, the stability of the catalysts was studied, showing that B-metal leaching is significant for both catalysts, with LaCoO3 being the most stable one.
